commit 6df2b42f upstream. We have one register for each EP to set the maximum packet size for both TX and RX. If for example an RX programming would happen before the previous TX transfer finishes we would reset the TX packet side. To fix this issue, only modify the TX or RX part of the register.

commit 5f63424a upstream. This patch adds support for recognition of ARM-USB-TINY(H) devices which are almost identical to ARM-USB-OCD(H) but lacking separate barrel jack and serial console. By suggestion from Johan Hovold it is possible to replace ftdi_jtag_quirk with a bit more generic construction. Since all Olimex-ARM debuggers has exactly two ports, we could safely always use only second port within the debugger family. Signed-off-by:

commit bb246681 upstream. Commit 557aaa7f ("ft232: support the ASYNC_LOW_LATENCY flag") enables unprivileged users to set the FTDI latency timer, but there was a logic flaw that skipped sending the corresponding USB control message to the device. Specifically, the device latency timer would not be updated until next open, something which was later also inadvertently broken by commit c19db4c9 ("USB: ftdi_sio: set device latency timeout at port probe"). A recent commit c6dce262 ("USB: serial: ftdi_sio: fix extreme low-latency setting") disabled the low-latency mode by default so we now need this fix to allow unprivileged users to again enable it.

commit b9a985db upstream. The code can potentially sleep for an indefinite amount of time in zap_pid_ns_processes triggering the hung task timeout, and increasing the system average. This is undesirable. Sleep with a task state of TASK_INTERRUPTIBLE instead of TASK_UNINTERRUPTIBLE to remove these undesirable side effects. Apparently under heavy load this has been allowing Chrome to trigger the hung time task timeout error and cause ChromeOS to reboot. Reported-by:

commit c90722b5 upstream. Commit 43530b69 ("regulator: Use regmap_read/write(), regmap_update_bits functions directly") intended to replace working inline helper functions with standard regmap calls. However, it also inverted the set/clear logic of the "CORE ADJ Allowed" bit. That patch was clearly never tested, since without that bit cleared, the core VDCDC1 voltage output does not react to I2C configuration changes. This patch fixes the issue by clearing the bit as in the original, correct implementation. Note for stable back porting that, due to subsequent driver churn, this patch will not apply on every kernel version.

commit 1ac202e9 upstream. Modifying the attributes of a file makes ima_inode_post_setattr reset the IMA cache flags. So if the file, which has just been created, is opened a second time before the first file descriptor is closed, verification fails since the security.ima xattr has not been written yet. We therefore have to look at the IMA_NEW_FILE even if the file already existed. With this patch there should no longer be an error when cat tries to open testfile: $ rm -f testfile $ ( echo test >&3 ; touch testfile ; cat testfile ) 3>testfile A file being new is no reason to accept that it is missing a digital signature demanded by the policy.

commit 3c8cb9ad upstream. Command buffers (skb's) are allocated by the main driver, and freed upon the last use. That last use is often in mwifiex_free_cmd_buffer(). In the meantime, if the command buffer gets used by the PCI driver, we map it as DMA-able, and store the mapping information in the 'cb' memory. However, if a command was in-flight when resetting the device (and therefore was still mapped), we don't get a chance to unmap this memory until after the core has cleaned up its command handling. Let's keep a refcount within the PCI driver, so we ensure the memory only gets freed after we've finished unmapping it. Noticed by KASAN when forcing a reset via: echo 1 > /sys/bus/pci/.../reset The same code path can presumably be exercised in remove() and shutdown().

commit 1b0fb5a5 upstream. __get_memory_limit() tests if dm_bufio_cache_size changed and calls __cache_size_refresh() if it did. It takes dm_bufio_clients_lock while it already holds the client lock. However, lock ordering is violated because in cleanup_old_buffers() dm_bufio_clients_lock is taken before the client lock. This results in a possible deadlock and lockdep engine warning. Fix this deadlock by changing mutex_lock() to mutex_trylock(). If the lock can't be taken, it will be re-checked next time when a new buffer is allocated. Also add "unlikely" to the if condition, so that the optimizer assumes that the condition is false. Signed-off-by:

commit af368027 upstream. ALSA timer ioctls have an open race and this may lead to a use-after-free of timer instance object. A simplistic fix is to make each ioctl exclusive. We have already tread_sem for controlling the tread, and extend this as a global mutex to be applied to each ioctl. The downside is, of course, the worse concurrency. But these ioctls aren't to be parallel accessible, in anyway, so it should be fine to serialize there. Reported-by:

commit 29d64551 upstream. Until now, hitting this BUG_ON caused a recursive oops (because oops handling involves do_exit(), which calls into the scheduler, which in turn raises an oops), which caused stuff below the stack to be overwritten until a panic happened (e.g. via an oops in interrupt context, caused by the overwritten CPU index in the thread_info). Just panic directly. Signed-off-by:

commit 205e1e25 upstream. Matt reported that we have a NULL pointer dereference in ppp_pernet() from ppp_connect_channel(), i.e. pch->chan_net is NULL. This is due to that a parallel ppp_unregister_channel() could happen while we are in ppp_connect_channel(), during which pch->chan_net set to NULL. Since we need a reference to net per channel, it makes sense to sync the refcnt with the life time of the channel, therefore we should release this reference when we destroy it.
